Reserachers at the University of Zurich's Dalle Molle Institute for Artificial Intelligence is developing a drone system that is capable of autonomously searching for lost hikers in the mountain sides. Drones may find it easy to fly in high altitudes but find it difficult to manouver in complex environments. In order to overcome this, researchers uses deep learning and artificial intelligence to impart into the navigational system of drones so that they may be of use in the search for lost climbers.
